Answer:
1.Small cell: has larger surface-area to volume ratio
Bigger Cell: has little space to volume ratio
2. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.
Amoeba and some bacteria's are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.
Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.
3. Diffusion and Cell Size
The larger a cell is, the greater the surface area available for diffusion. ... Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
The trait distribution most likely change over this time such that the plants with favorable traits, medium-tip leaves and drip-tip leaves will survive due to natural selection.
<h3>What is natural selection?</h3>
Natural selection is the process by which organisms which are better suited to their environment survive whereas those not suited die off.
The organisms that are suited to their environment possess special features which enable them to adapt to changes in their environment.
Considering the plants in the rainforest with different leaf tips:
- Trait A: medium-tip leaves
- Trait B: drip-tip leaves
- Trait C: wide-tip leaves
Since fungi grow in moist environments, it can be seen that plants with Trait C will be least favored to survive, while plants with Trait B will be most favored to survive by natural selection.
Thus;
- In year 1: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves.
- In year 5: the composition of plants is 50% have medium-tip leaves, 25% have wide-tip leaves, and 0 % have drip-tip leaves
- In year 10: the composition of plants is 25% have medium-tip leaves, 75% have wide-tip leaves, and 0% have drip-tip leaves.
In conclusion, plants with favorable traits will survive due to natural selection.

Most animals ingest their food and then digest it in some kind of internal cavity. </span>Somewhere around 9 or 10 million species of animals inhabit the earth.
About 800,000 species have been identified.
